How can we improve VoNR quality and drops in 5G SA apart from tilt?

Hello Experts.

How can we improve VoNR quality and drops in 5G SA apart from tilt?

Which basics parameter to be checked?

VoNR DT KPIs are very bad. Mainly VoNR drops and muting RF is bad.

Vendor is Ericsson.

It depends on radio planning too.

If you have a site every 3 km there isn’t much you can do.

Do you have this problem in rural or in city?

City

Within 300 ISD.

Data drive KPI is ok, but VoNR is very bad - mainly drops and muting.

As in VoLTE we have ROHC feature, TTI bundling… so does VoNR must also have this kind of feature, right?
